"Old men do it better. We're not so sensitive in certain areas"

This quote by Robert Plant is likely describing the idea that older people have more experience and knowledge than more youthful people. He is suggesting that older people are better at certain things because they are not as sensitive as more youthful people. This could mean that older people are much better at making choices, as they are less likely to be swayed by feelings or outside impacts. They might also be much better at managing difficult situations, as they have more experience and are less likely to be overwhelmed by the circumstance. In addition, older people may be better at understanding the intricacies of life, as they have seen more of it and have actually had more time to review it. Ultimately, Robert Plant is recommending that older people have a specific benefit when it pertains to particular locations of life.
